How to Pass and Use CSRF Token in WebSocket API Calls in Frappe

I am working on a project where real-time data is transmitted between the client and the server using WebSockets. For this, I am using socket.io in the Frappe Node.js real-time service.

In my setup, I need to make API calls from the Node.js server (using WebSocket events) to the Frappe Python server. Since Frappe requires a CSRF token for secured API calls, I am exploring the best way to pass the CSRF token and use it in these scenarios.

Use the CSRF token as a request header (X-Frappe-CSRF-Token) in API calls made from Node.js (via frappe_request or fetch) to the Python server.

so how can i access CSRF token in Frappe Node server ie., in “apps/frappe/realtime/handlers/frappe_handlers.js”
